Procedures to Complete Testing and Follow-Up Flashcards
What is the purpose of cabling system certification?
To ensure installation is fault-free and will perform properly according to the end users requirements
What is the basic link?
Permanent portion of the cable run from (not including) the cross-connect or patch panel to the work-area outlet
What portion does the channel link test add to the basic link test?
Patching or equipment cords, work-area cable
Explain why is it important to mark Category 5 cables before installation
Cat 5 cable almost completely cancels external signals, so a test tone cannot be detected through the cable jacket, making cables difficult to trace
What is the purpose of testing cable after the cable is pulled in and punched down on the cross-connects and outlets?
Eliminate the cabling system as a possible source of network problems when troubleshooting
Identify the three phases of testing
Visual inspection, testing using appropriate field testers, documentation
Identify the three (physical) areas that need to be visually inspected
Pathways and spaces, telecommunications closets, equipment rooms
Identify four parts of the cabling system that require visual inspection
Infrastructure, grounding and bonding, cable placement, cable termination, equipment and patch cords, proper component labelling
Which tester is a good, general, multi-purpose type?
Volt-ohm-milliampere multimeter
What is the amplifier/tone generator test equipment commonly used for?
Cable identification and troubleshooting
Which low cost tester can identify opens, shorts, crossed pairs and miswires?
Wire map tester
Which test units are able to verify the EIA/TIA TSB-67 transmission performance requirements?
Certification test units
What is an attenuation test?
A measure of the signal loss from one end of the link to the other
The _________ is a measure of analogue signal strength
“bel”
What is crosstalk?
Crosstalk is the unplanned transfer of information from one circuit to another circuit
